Yes, I agree with the statement that rapid environmental degradation is causing a serious threat to security.

To qualify as a security problem, an issue must threaten the very existence of a state or group of people. Security relates only to extremely dangerous threats that could endanger core values beyond repair if not addressed. Environmental degradation meets this criterion as it poses existential threats to nations and their populations.

Environmental degradation, particularly global warming, emerged as a major security concern in the 1990s as part of the idea of global security. It represents a non-traditional conception of security that focuses on the changing nature of threats. Unlike traditional military threats, environmental threats are global in nature and transcend national boundaries.

The threat is particularly severe for certain countries. For instance, the Maldives faces an existential threat as a large part of its territory may be submerged due to rising sea levels. A sea level rise of 1.5–2.0 meters would flood 20 percent of Bangladesh and threaten nearly half the population of Thailand. This demonstrates how one country may disproportionately bear the brunt of a global problem.

Since environmental problems are global in nature, no country can resolve them alone. International cooperation is vital to address these threats, though it is difficult to achieve. Thus, environmental degradation constitutes a serious security threat as it endangers the very existence of nations.
