Introduction

Animal and plant species are becoming extinct at an alarming rate. It has been estimated that in the rain forests alone, over a hundred plant, animal and insect species are lost each day, which translates to 50,000 species a year. The most biologically diverse areas of the world tend to see the greatest species extinction. Hence, the rainforest and coral reef, known as the "rainforest of the sea," tend to be at the center of many researchers' concern. Overwhelming evidence suggests that the loss of biodiversity in these habitats is a direct cause of plant and animal extinction. Here are a few reasons that could be cited for preventing extinction of a species:

How can we prevent it?

As part of the design process, engineers listen to environmental scientists to gather information that will help them design products to fight extinction. For example, some scientific studies have shown that greenhouse gas emissions have contributed to global warming, which in turn could endanger some plants and animals. Using this scientific evidence, engineers can design products (like cars) that reduce harmful emissions as a way of reducing the risk of extinction. Engineers create both direct and indirect solutions to prevent extinction: materials engineers are developing long-term alternatives to wood; architectural engineers are making buildings more energy efficient; mechanical and chemical engineers are producing clean energy; and civil and other engineers are working to save coral reefs.  Engineers have a major role to play in the prevention of extinction.
