Overfishing species like tuna, cod, and sardines disrupts the balance of the bay ecosystem by removing key predators and competitors that help maintain the population of herbivores, such as sea urchins. With fewer predators to control their numbers, sea urchins can proliferate and overgraze on kelp, leading to significant declines in kelp forests. These kelp forests are crucial for providing habitat and food for various marine species, and their loss can further destabilize the ecosystem. Consequently, overfishing can initiate a cascade of ecological changes that ultimately harm biodiversity and the overall health of the bay.

Electric geysers contribute to environmental degradation primarily through their reliance on electricity, which often comes from fossil fuels, leading to greenhouse gas emissions and climate change. Additionally, the manufacturing and disposal of electric geysers can result in resource depletion and increased waste, especially if they contain non-recyclable materials. Furthermore, their energy consumption can strain local energy grids, exacerbating environmental impacts associated with energy production.

Water, forests, and wildlife are considered renewable resources because they can naturally replenish themselves over time. Water cycles through the environment via processes like evaporation and precipitation, while forests regenerate through growth and reforestation. Wildlife populations can recover if managed sustainably, allowing for hunting and fishing without depleting their numbers. However, the sustainability of these resources depends on responsible management and conservation efforts.

Renewable resources are naturally replenished over short time frames, such as solar, wind, and hydro energy, allowing for sustainable use without depleting the resource. In contrast, non-renewable resources, like fossil fuels and minerals, are finite and can take millions of years to form, leading to depletion with continued extraction. The use of renewable resources typically results in lower environmental impact and contributes to reducing greenhouse gas emissions, while non-renewable resources often result in pollution and habitat destruction. As a result, transitioning to renewable resources is essential for sustainable development.

The geosphere, which includes the Earth's rocks, soil, and landforms, plays a crucial role in water pollution by influencing the movement and quality of water. Pollutants can leach from the soil into groundwater or surface water systems, particularly in areas with poor soil drainage or contamination from industrial activities. Additionally, erosion and sediment runoff can carry pollutants into water bodies, further degrading water quality. The geological composition also affects the natural filtration processes that can mitigate or exacerbate water pollution.

The Clean Development Mechanism (CDM) is a key component of the Kyoto Protocol, allowing industrialized countries to invest in emission reduction projects in developing countries as a way to meet their own greenhouse gas reduction targets. By facilitating technology transfer and sustainable development, CDM projects generate certified emission reductions (CERs), which can be traded or used by developed countries to offset their emissions. This mechanism promotes cost-effective solutions for reducing global emissions while supporting economic growth in developing nations. Overall, CDM aims to enhance global environmental integrity and foster climate cooperation.

Businesses often believe that environmental laws can impose significant costs and regulatory burdens, which may hinder their competitiveness and profitability.
