In the four environmental concerns (biodiversity, deforestation, pollution and climate change), which would you pick as deserving s the most urgent attention and why?
Climate change deserves the most urgent attention. Due to the industrial developments witnessed globally, emission of greenhouse gases has been on the rise. It occurs largely as a result of the combustion of fossil fuels, emissions from agriculture and pastoralism, and land-use changes that accompany the destruction, clearance and burning of forests. Climate change already has observable ecological and social effects, and its projected impacts could potentially result in profound changes in global mean surface temperature, sea level, ocean circulation, precipitation patterns, climatic zones, species distributions and ecosystem function.
