Write a short paragrand about oxygen.You should include: a) Where oxygen comes from b) Why we need oxygen.

Our environment is increasingly polluted by plastic bag waste. Plastic bags mixed into the soil prevent oxygen from passing through the soil, slowing the growth of crops, causing soil erosion. Plastic bags and drains, trenches, canals, canals will clog causing flooding. If we do not take measures to limit the use of plastic bags immediately, soon canals, fields, everywhere will be filled with plastic waste, the environment will be heavily polluted. So, when using bags, especially food packages, use alternative materials such as paper and leaves. We need to propagate to everyone around us about the harmful effects of plastic bags on the environment and together change this bad habit. NGuyên xin hay nhất
