Read carefully the paragraph below, and choose the best answer.
It is human activity that is causing the rise in global temperatures and it must be human activity that changes in order to stop or slow the increase. Improving fuel efficiency standards for cards and trucks, using public transport, riding a bicycle, scooter or skateboard, planting trees, turning off unnecessary lights, recycling, and buying locally produced goods, including food, will all help to slow the rate of climate change. There is much that people can do on an individual level to minimize our own “carbon contribution”. In addition, the observation of our actions can inspire others to make the same changes in their own lifestyles.
