Nowadays, the development of human world causes many bad effects to the environment. We throw garbage everywhere, exploit too much natural resources or contaminate the air. Therefore, our environment is being seriously polluted and we need to protect it from now. First of all, we should reduce, reuse and recycle. Instead of using plastic bags, we can use leaves to wrap food. We can recycle plastic bottles, cans, paper to reduce garbage. Using public transports and decreasing the number of motorbikes and cars are also good ways to reduce carbonic in the air. Besides, we should purify contaminated lakes or rivers in order to lessen the pollution in the water. Last but not least, the government should encourage everyone to take action together. Especially, we need to punish people who contaminate the environment. In conclusion, the Earth is our home so protecting it is everyone's responsibility.
Solar energy is the key to our future. If we do not use it, our planet will not survive. We do not have enough resources on Earth to supply our energy needs. We are slowly using solar energy more. Most places you go in the world today you can see solar panels on people’s houses. I hope that in the future, all houses will use solar power. It’s so simple. In fact, it’s free. All you have to do is pay for the solar panels and some other equipment, and then you have free energy. I think in the future it will be everywhere. We’ll wear clothes that provide solar power, and we’ll drive cars powered by solar energy.
