This document contains summaries of several issues: 1) Land degradation and depletion of resources are threatening many developing countries as human activities negatively impact the environment. Global warming is also a concern. 2) Water conservation is needed as many areas face drought. Local governments implement strategies like public education, tiered water pricing, and limits on outdoor watering. 3) Tiger populations in India and Nepal have sharply declined due to hunting, with only around 1,141 tigers remaining in India. Tigers face a high risk of extinction. 4) Global warming has increased global temperatures over 1 degree Fahrenheit since 1900, largely due to human emissions of greenhouse gases. Urgent action is needed to address this issue.
