there is little doubt that the planet is warming. over the last century, the planets temperature has risen by around 1 degree fahrenheit (0.6 of a degree celsius). the warmest since the mid 1800?ˉs was the 1990s. the hottest years recorded were 1997, 1998, 2014, 2014, 2014.

the united nations panel on climate change projects that the global temperatures will rise 3-10 degrees fahrenheit by the century?ˉs end - enough to have the polar caps all but melted.if the ice caps melt, a vast majority of our countries borders will be under water. monuments and great buildings, as well as homes and lives will be under water, including new york city.

so now we know what some of the causes are for global warming, how can we as individuals do our part to help save the planet?

the answer is simpler than you may think. you don?ˉt have to go miles away from home to protest, or spend masses of money. if you try to follow the few simple steps that i shall now give you, you will have started to help us all.

firstly, plant a tree. this could be easier than it sounds. join or help out a local wildlife group and ask to plant a tree. trees, when fully grown, will help keep the planet cooler. on the same point, you could protest against the demolition of the rainforests. this is the same principle, we need the trees to cool our planet and yet they are chopping them down to create roads or homes.

something as simple as walking instead of taking the car will help reduce pollution. as well as stopping pollution, you are giving yourself exercise, something important for our bodies. so the next time you get into your car, or your motorbike, think - do i have to make this journey by vehicle or can i walk?

when you are at home, and your getting a little cold. put a jumper on and do not adjust the heating.the extra heat produced by our homes also affects the planet. so try wearing an extra layer in winter.

if possible, buy your fruit and vegetables from local suppliers. and try to avoid imported goods. the more foreign food that we import the more pollution from aeroplanes and boats it will create.

keeping to the speed limit can also help the environment. the more you speed the more petrol you are going to use, making the pollution higher. also, suv?ˉs make about six times their own weight in co2 each year. a small efficient diesel car covering the same distance not only uses much less fuel; it makes two thirds less.

if possible use solar energy, after all it is free; all you need to buy is the equipment. you can get much of your hot water and heating from the sun and even generate electricity.

reduce, reuse and recycle. only buy what you need; don?ˉt stock the cupboards with ……此处隐藏1055个字……the global temperature to go up.

however, the attitudes of scientists towards this rise are completely different. on the one hand, it’s predicted that there may be a rise of several metres in the sea level, extreme climate change or the disappearance of species. on the other hand, it’s supposed that the rise will make plants grow quicker and produce more, thus encouraging a greater range of animals.

it seems that the topic is controversial and there is a long way to go.
