Recently, scientists have discovered that our environment is changing for the worse. There are some causes and effects about global warming and the holes in the ozone layer. Why we are experiencing global warminjg and holes in the ozone layer is because a lot of factories manufacture poison and pollution without recycling. Coal is plentiful and the cheapest resource in the world and the mass of CO2 is produced from coal.
People also cut down many trees for wood or burn them to clear land for farming, therefore de-forestation will decrease the amount of CO2 being absorbed. Moreover, CO2 is the main gas causing global warming. The other problem is scientists found a hole in the ozone layer near Antarctica. People using air conditioners, refrigerators and aerosol cans containing CFCs will destroy the ozone layer.
Global warming causes extreme weather. For instance, glaciers melting, sea levels rising and flooding. A place that has never had tornadoes is now experiencing them. Places susceptible to drought are drier than before. If sea levels rise, we will lose a lot of land and a lack of fresh water. Then, many habitats will disappear and animals will become extinct. We'll probably get epidemics because of extreme weather. The hole in the ozone layer allows ultraviolet radiation fo directly into the Earth. People will also get skin cancer more easily.
Altogether, we should cherish our Earth or destruction will happen one day. I think if everyone does their best, the Earth will get better. In my opion, if we could
