Some people think that the human activities are harming the world. Others think that it is making the earth better place to live...
I think that people can't live without the human activities and I have facts for it.

At first the human activities made our lives easier,that way that if you want to see a man and you have an important conversation you just call him and talk to him,before people traveled for weeks and days so they can meet his friend.Or if you want to travel you just do that for 2 or 3 hours not for days or weeks.

Second is the driving.So the driving is not a big problem,because if the government doesn't want polluted air they can put rule to make the cars without their fumes.Another thing is recycling.Some of the countries they don't do it but if they watch how they can recycle they can learn then teach others.

At last the electricity.If we didn't have the electricity we would have lived with candles.And if you didn't know the smoke that is coming out of the candle is dangerous.The technology is other kind of human activities and now everybody uses.And the other thing is experiments that the people are doing it.

In the conclusion people are using the human activities and it's making the earth better and our lives easier we need to plant more trees and recycle more.

 Some people believe that the Earth is being harmed by human activities. Others feel that human activity matters the Earth a better place to live.

 When we remember how people were living years ago without technology ,we think it’s just impossible for us. Year by year people created and continue creating new things that are helping the Earth to evolve. But at the same time the Earth is being harmed by things that people do. Different people have different ideas and think in a different way. Some people say that human activities are harming the Earth, others say that human activities are helping the Earth to evolve.

 Personally I think that the Earth is being harmed by human activities.

First of all I want to talk about the air that we breath. We always breath pollution and dust. The pollution is coming from cars and factories. Though 100 years ago there weren't any cars. People used to move by using the animals. And none of the animals make pollution when it moves.It’s so good that the Earth is developed now, but it’s polluting it too. Nowadays in small cities are million of cars and factories. For example before people used to think about plants and animals . But now people build factories without even thinking of animals and plants that live near the factory. This is a huge problem for our Earth and people should think about reducing pollution.

The second reason I want to give is about tress. For example people used to chop down the trees for getting papers an some wood. But now they chop old trees because they aren't useful, without even thinking that every tree is making oxygen to breath.

The last thing I want to talk about are animals . Their lives are in danger . For example human kill the animals to get their fur to make bags and shoes. Some animals for example fishes are being killed in the water by the pollution that factories make.Animals are being killed by human activities and some of their lives are in danger and some of them are disappearing too.

In a conclusion I have to say that human activities are harming the Earth and everyone should think before doing something that causes the Earth.

                                 Human activities
Some people believe that human activities is harming the Earth. Others think human activities makes the Earth a better place...
In my opinion I think that human activity is harming us the environment and the animals and I have the facts to prove them.

First of all, human activities contribute to climate change by causing changes in the Earths atmosphere in the amount of greenhouse gases. for example as we burn fossil fuel like coal and natural gas we are increasing the amount of greenhouse gases in the Earths atmosphere which causes the climate change in the Earth.

Second of all, floods are not only causing destructions to cities but also take peoples lives away... Because of cutting down trees for personal benefits, tree roots cannot hold the soil in place to absorb water from the soil making soil unable to store more rainwater which leads to flood. For example in this century we are getting more floods and more deaths from it because of the lack of trees and plants in our cities. 

Furthermore, the toxic that is being released from our factories as we all know is polluting the air and water and because of that a lot of homeless people do not have safe and clean water. that toxic from the factories is not only polluting water and air its also giving new several deadly diseases which endangers human life like Ebola, Malaria, HIV, Influenza.

Last but not least, by doing all of this activities we are putting animals lives in danger. For example as the human population grows and the rich countries continue to consume recources at voracious rates we are crowding out, poisoning and eating all other species into extinction. The most endangered animals in the world are polar bears, mississippe gopher frogs, long head sea turtles, kit foxes etc.

In conclusion, if humans continue to do the same mistake the Earth will be in danger and people won't live healthy and won't live in a healthy lifestyle :O.

human activities make the life of the people a lot easier and  faster to do something but on the other side it could cause some serious problems to our earth  but people don't have better option to do something better than the"human activities" to make our lives easier. i personally think that human activities  are  harming our earth for the following.
scientists say that human activities are causing global warming to our earth and the main reason is gasses . for example when the human started bringing fuel , inventing technology like nuclear missiles that include a lot of different gasses inside them and when the all the gasses mixes in the air it starts causing global warming. the other warning is the decrement of the water , if people were more intelligent and know how to save water there would be less problems and there is a very similar example of this : The Aral Sea, located on the Uzbekistan-Kazakhstan border, was once the fourth largest lake, but has now shrunk by 75 percent. The Aral Sea was once fed by two major rivers which now, due to human activity.Another reason is plastic productions , people invented a material, called plastics, that were previously unknown to the planet. Many of these new materials are made up of chemical compounds that can remain active in the environment for thousands of years. Today, the world produces approximately 300 million tons of plastics each year. About 20-40 percent of that ends up in landfills, and another 10-20 million tons makes it way to the oceans, disrupting sea life. According to the World Watch Institute, “a recent study conservatively estimated that 5.25 trillion plastic particles weighing a total of 268,940 tons are currently floating in the world’s oceans.” and that is a very huge amount of dangerous material in the oceans which will cause serious problem in the future.

if people continue doing worse human activities the world would be in danger but on the other hand if human activities were not excisted the population would increased by huge amount and the world would be in danger too because the human activities will cause people die earlier.

                                Human activities 
Since the day us humans were created technology has improved,how we think is improved and the things we can do/make today or even in the future is absolutely incredible. How ever  not all of this ''improvements'' are improvements, some of them are damaging the planet that we live in .So the question you have been waiting for, Are human activities good or bad ?? In my opinion Human activities are something good to have in our planet and I am going to prove and give examples why it is good.
   
First of all human activities have made all of our lives better in so many ways that now we don't even have to travel to see someone because we can just open the internet and contact the one we want to see or now if we want to travel we don't have to do it in a couple days or weeks we can just do it in a matter of hours.For example before people traveled with animals and that took days,weeks or months and now it has become so easy and we don't waste alot of time.

Second thing is we can improve all the bad things by not driving a alot of cars and another thing to do is recycling everything that we can.For example alot of countries have the problem of not recycling and we can all improve that if we just care a little bit,and by that we can make human activities all positive.

The last thing is that if we all think properly we would know that air pollution and all that stuff that are considered bad are not actually bad because if we didn't have the stuff that can kill is we'd have the problem of overpopulation and in my opinion that is alot worse then the air being polluted or something .For example if we didn't have these problems we would have overpopulation and I think it take us a couple hundred years to die and if that continued of course in my opinion it would be all world war again we would kill each other for survival and etc.

For conclusion Human activities are good and all of us are using it today and it is making our lives so much easier and if we just care a little bit like plant more trees,recycle the world would be just perfect.

My presentation is about global warming witch is a huge problem for our society. We as human expect a lot from nature ,but are we giving the same thing back ? The answer is yes,but we are giving it polluted and changed. For example nature is giving us air , but we are giving him back pollution. The forests  that helps us a lot in every way are being destructed. In order to make our world we are destroying world’s family, which includes animals,birds and insects .One of the problems of global warming is deforestation. One cause of deforestation is the use of forests in a wrong way.In order to save wood and other products, we are chopping the forests to have not as much important things as we need. Forests are necessary , they clean the air,they act as natural filters remove and store carbon dioxide . Because of that deforestation releases large amounts of carbon .

Ice melting is a reason of global warming too.Increase in sea levels is the result of melting of two massive ice sheets in Antarctica and Greenland as researched by scientists. Many nations around the world will experience the effects of rising sea levels,which could displace millions of people. The Maldives a country is already looking for a new home due to rising sea levels. Majority of Americans living in coastal states ,are facing large impacts due to global warming .Seawater expands ,takes more space in the ocean and causes a surplus rise in water level and also the melting of ice over land ,which then adds water to the ocean. Some of the sea lions,sea urchins,kelp beds,and fish populations,appears  to have extinct due to loss of plankton ,decrease in populations of sea lions ,leading orcas to eat too many sea otters ,leading to urchin explosions ,leading to loss of various fish populations. Water vapor is increasing in the atmosphere due to carbon dioxide –induces warming.Two-thirds of the heat trapped by greenhouse gases in contains in water vapor ,and as the average temperature on the planet to raises ,the amount of water vapor rises in turn,leading to untimely rainfall which may further cause other natural calamities such as floods. Sunspots are dark patches on sun’s surface that block hot solar plasma. Surrounding sunspots are bright patches known as facule . These patches give off greater than normal radiation ,and they are more powerful than the darker,cooler patches.This means that the total average energy over a 30 day solar rotation increases,which gives way too many other after effects. Each time  a fossil fuel burn ,carbon dioxide level in the atmosphere increase .Auto mobiles ,carbon emissions from the burning of gasoline to power cars ,trucks , and other methods of transportation. Electricity generation requires ,coal  is the largest producer of carbon dioxide emissions. Counties across he world want to switch to nuclear power plants. Mining oil ,coal and other mineral products underlying in deep beds allow methane,a greenhouse gas, to escape from the Earth. Disturbing the soil,stored gases make their way into the environment.

poverty

poverty is when people cant get their basic needs like food,clothing etc.

Types of poverty 

there are 4 types of poverty

1. Absolute poverty : the worst type of poverty when people cant get anything and they cant live a lot.
2. Relative poverty: is when people for example dont have the money to put their children in school/university or they cant buy presents for children at christmas.Even though they have access to government support for food, water, medicine and free housing, they are considered poor because the rest of the community have access have education.
3. situational poverty:People can be poor because of some adversities like earthquakes, floods etc. people can help themselves by getting assistant from other people in this situation.
4. the final type is Generational or Chronic Poverty:This is a more complicated type . It is when poverty is handed over to individuals and families from generations before them. In this type, there is usually no escape from it, as people are trapped in its causes and have no access to tools that will help them get out of it.

causes of poverty 

there are many causes but i will write about the main causes

1. not well income : If the national income is not very well among all communities in the country, there is a risk that poorer communities will end up poorer.
2. gender discrimination:for example in many african countries girls/women are not allowed to work or be in school and this can cause poverty because half of the country hasn't got any education 
3. war:many countries need oil and for that reason they attack weaker countries that is rich with oil and they steal and destroy and this causes poverty to that country 
4. natural disasters:volcanos tsunamis earthquakes floods and many other natural disasters can cause serious problems/deaths/a lot of losses to the country.

where are the poor

the 80% of the poor is in africa,south asia and latin america.

they have been known to have large areas of poverty.

Countries in this region include Angola, Guinea, Liberia, Mali, Somalia, Sudan and Zambia.

In these countries most of the people live in less than 1$ a day.

the effects of poverty 

Hunger, Health and Deaths.
Absolute poverty results in extreme hunger, starvation and malnutrition. People (and children) become vulnerable to preventable diseases such as cholera, dysentery and tuberculosis, with no access to health services and medications. Death rates rise.

Relative poverty is  better than the previous one, it may not cause starvation , but on the other hand they cant always eat healthy and it may cause weakness to them.

the vicious cycle of poverty 

1. high amount of child births 
2. poor household
3. no food,unhealthy water,no school
4. as they drink unhealthy and have no education they wont have energy/skills to work
5. low productivity
6. they might get a little income or no income
7. no self esteem,no personal control 

reducing/solving the poverty

here are the best solutions of poverty

1. education:quality education can really help people take knowledge,information and life skills.Building schools,training teaches.
2. increase income rate:as they get good education , skills to work, they get better jobs and increase their income rate , but first they have to get quality education
3. health,food,water: many rich countries can donate food/medicines and this can help them have more energy to work and stay healthy.  

Facts about poverty

did you know that:

1. Nearly 1/2 of the world’s population — more than 3 billion people — live on less than $2.50 a day. More than 1.3 billion live in extreme poverty — less than $1.25 a day.
2. 1 billion children worldwide are living in poverty. According to UNICEF, 22,000 children die each day due to poverty.
3. 805 million people worldwide do not have enough food to eat.
4. More than 750 million people lack adequate access to clean drinking water.and this kills more than 850,000 people every year 
5. In 2011, 165 million children under the age 5 were died 
6. 1.6 billion people live without electricity.

thank you i hope you have learned something new about poverty.

                                                     Global warming                             Hi my name is Avo...

Today I'm going to talk about a serious problem global warming . First I'm going to explain the dangers of it then give you solutions for it.

Global warming is primarily a problem of too much greenhouse gases in our atmosphere. for example as we are burning fossil fuels like coal or natural gas or if we are cutting down trees and burning forests we increasing the amount of greenhouse gases in the earths atmosphere.

                                        Greenhouse gases

Greenhouse gases are gases in the earths atmosphere. The primary gases are carbon dioxide, Methane, Nitrous oxide.

1. Methane (CH4): it's the main component of natural gas but it's also produced when organic maters decompose in absence of oxygen which happens flooded gardens or landfills. Methane has increased by 148% since the industrial age

2. Nitrous oxide (N2O): nitrous is produced when bacteria breakdown nitrogen compounds and soils in the oceans. N2O has increased by 18% since the industrial age

3. Carbon dioxide (CO2): Carbon dioxide is being produced when burning fossil fuels or as we generate electricity and when we drive. Carbon dioxide has increased by 39% since the industrial age.

                                        The suns radiation

  The suns radiation comes in forms of light waves heating up the earth. Some of the radiation that is absorbed and warms the earth is re radiated back in to space in the form of red waves, but some of the waves are trapped by the atmosphere and held inside it. So the problem is that the atmosphere is continuing to consist more and of greenhouse gases due to human kind. And therefore making the radiation from the sun become trapped on earth in which heats up the planet.

                                               Solutions

1. Eat your leftovers because when its going to landfills methane is coming out of them every second.

2. In winter you can wear sweaters in your home and turn down the heat a little bit because most homes are getting electricity from burning fossil fuels which increases the amount of carbon dioxide.

3. Instead of driving a car you can walk more or ride bikes more often which also keeps you healthy and fit.

4. Farmers should do more smart farming.

5. Traveling burns a lot of fossil fuel. So you can stay in your country and have vacations there.

6. Plant more trees and gardens.

I hope this topic was interesting for you and I hope learned something new today :D.    

                                                Cancer
Today I will write about types of cancer,causes and how to prevent it.
Some types of Cancer: (there are more than 100 types so I'm going to write the common ones:
Breast (male-Female):
Kidney.
lung.
leukemia (all types) It is the blood cancer.
Melanoma(skin cancer).

Lung Cancer: It is mostly caused because of smoking alot,for example is someone smokes 5 cigarettes per day they are highly increasing the chance of lung cancer.Teens these days think smoking is cool and then they spread the word and it becomes worse for everyone because they are polluting the air too.
Kidney:Changes mutations in genetics.DNA doesn't only effect how we look but also how our cells grow and die,certain genes that help cells grow,divide and stay alive are called oncogenes. Others that slow down cell division or kill the cells are called tumor genes.Cancer can be causes by DNA changes that turn on oncogenes or turn off tumor genes.
Leukemia is the cancer of the blood or bone marrow.This cancer can be caused because of the white cells being damaged in some way. Normal blood cells die after a time and other ones are replaced in the bone marrow.The bad cells do not die so easily and by time they multiply and leave no place for the normal ones.
Melanoma: Melanoma is the skin cancer.It is mainly caused because of the sun radiation or the tanning machines.the normal colors are black and brown but they can also be purple ,red,blue or white.
So how to prevent all this from happening:Eat healthy: eating healthy is a big part in our lives,any people got cancer because of drinking alcohol or eating fast food, some fruits such as grapes,strawberries,kiwi and blueberries can prevent cancer
Do not smoke
Be physically active: Every day you should walk at least 30 minutes.and also maintain a healthy weight.
