7. A non-renewable resource is a resource that doesn't renew itself . Examplesare coal, oil, natural gas, and uranium.Non-renewable sources pollute the environment. Renewable energy is theonethatcomes from resourceswhich are naturally replenished such as sunlight, wind, rain and geothermal heat.

8. After the cars appeared, it developed steadily. The cars became more aerodynamic , and so these don't pollute environment so much. Nowadays people develop a lot of environmentally-friendly technologies for example: biofuels, electric cars hybrid propulsion and so on. This helpsfor the environment, but these don't solve everything.
