Nowadays, the world is facing a number of pressing environmental problems, and over the next few weeks, we'll be discussing various innovations that may help solve these problems.To begin our discussion,I'd like you to think of one global environmental problem—for example, it could be related to water, air, land, climate,biodiversity, energy, or something similar. Then explain what you think would be an effective solution to this problem.

One of the major environmental problems is the limited freshwater supply in many areas of the world, which means that we need to find effective technologies to provide people with enough drinking water. One solution is to improve the technology for removing salt from seawater, which could allow us to use seawater to replenish dwindling freshwater supplies.

l think the biggest problem is the air pollution caused by the overuse of motorized vehicles.The obvious solution is for local governments to promote alternatives, like building bike lanes in cities or improving public transportation with electric buses.Both of these would be easy to implement as well.
