A note on PSA testing: Prostate cancer, meaning cancer of the prostate gland, is a common adenocarcinoma in men. The probability of getting prostate cancer rises with age. It is generally treated by surgically removing the small prostate gland or with radiation. It is generally detected by high PSA levels and / or by surgical biopsies.
Sustainability is the âreframingâ of the debate over human-environment relationship critical to ensuring quality of life for future generations â whether the human life-support system on earth can continue indefinitely, or whether it is changing the world in radical ways that will lead to new, undesirable states for people and the planet.
In ecology, sustainability (from sustain and ability) is the property of biological systems to remain diverse and productive indefinitely. Long-lived and healthy wetlands and forests are examples of sustainable biological systems. In more general terms, sustainability is the endurance of systems and processes. The organizing principle for sustainability is sustainable development, which includes the four interconnected domains: ecology, economics, politics and culture. Sustainability science is the study of sustainable development and environmental science.
