Problem or the earth

The human have been receiving benefits of our own planet.As long as we want to receive benefits from earth,it is necessary to look after everybody.But can we do it?I don`t think so.Not only do we don`t love the environmental,but also we destroy it.Therefore,the earth has been raging and deprecating our activities.Bellow,I am saying about some problems in my opinion.
. Nowadays mankind confronts environmental problems more often than ever. Animals and birds extinction, air and water pollution, excessive use of natural resources, recycling, climate changes, disregard of environmental concerns make car pollution topical
.Earth of its thin layer of topsoil through water and wind erosion, destroying this precious micro ecosystem that takes centuries to form and supports all life on land. Furthermore, bee populations are plummeting, and over 70% of our food is pollinated by bees; if bee populations fall too far, our food supplies will be seriously threatened
Next planet of problem is lot of contagion .Every people want live painless. Doctors have trying to treated all sick.But it have inabilitied. Cause of contagion : improper food,dope,air pollution and misery etc. Riddancing ways and means from it disastrous contagion is peoples love each other.

Our most dream is healthy and happy life. Owner of one world we can’t live without locality.I wish I didn’t destroyed it planet.We all love our world and we have lived it planet.


I hate pollution. Keeping recycle bens in the kitchen may help to stop people from accidentally throwing into the trash an item that could have been recycled. Some recyclable items include glass, paper, and most types of mettle. You want to be sure that glass, paper and mettle are all separated into different bins. Once these bins are full of recyclable materials they can be given to your local recycle center.
Air pollution is actually the addition of any harmful substances to the atmosphere, which causes the damaging of the environment, human health and the quality of life. With the development in industry, came along the increase in air pollution, which occurs inside homes, schools, offices even in the countryside.
Trash is a big problem in the world we have so many trash we throw away. Is it your turn to take out the trash? Chances are, your trash barrel is a lot lighter now that your family is recycling. Several years ago, people in Wisconsin threw out everything from toothpaste tubes to old TV sets, food scraps to bags, computer games to oil filters. The world is currently growing at a rate of 79,000,000 people per year – more than ever before – and as more time passes that number will rapidly increase. The world population is predicted to be over 10 billion in 40 years, and will become greater and greater as the ever-growing human species continues to breed.
