What is the biggest cause of environmental degradation and biodiversity and environmental factors that influence the survival of organisms in ecosystem?
The biggest cause of environmental degradation and biodiversity loss is human activities. Anthropogenic (human-caused) factors have a significant impact on the environment and the delicate balance of ecosystems.
Some of the major human-induced causes of environmental degradation and biodiversity loss include:
Habitat Destruction and Fragmentation: Deforestation, urbanization, and conversion of natural habitats for agriculture and infrastructure development lead to the destruction and fragmentation of ecosystems. This disrupts the habitats of many plant and animal species, leading to population declines and loss of biodiversity.
Pollution: Pollution of air, water, and soil from industrial activities, agriculture, and improper waste disposal has harmful effects on both terrestrial and aquatic ecosystems. Pollutants can directly harm organisms and disrupt ecological processes, leading to a decline in species diversity.
Climate Change: Human activities, particularly the burning of fossil fuels, release greenhouse gases into the atmosphere, causing global climate change. Climate change alters temperature and precipitation patterns, sea levels, and extreme weather events, affecting ecosystems and species' distributions worldwide.
Overexploitation: Unsustainable harvesting of natural resources, such as overfishing, poaching, and logging, can deplete populations and lead to the decline or extinction of many species.
Invasive Species: The introduction of non-native species to new environments, either intentionally or accidentally, can have detrimental effects on native biodiversity. Invasive species can outcompete or prey upon native species, disrupt ecological interactions, and alter ecosystem dynamics.

Now, let's explore the environmental factors that influence the survival of organisms in an ecosystem:
Temperature: Temperature affects the metabolism and physiological processes of organisms. Each species has an optimal temperature range in which it can thrive. Extreme temperatures can be stressful or lethal to organisms.
Precipitation: The amount and timing of precipitation influence the availability of water for plants and animals. Droughts and excessive rainfall can impact the survival of species.
Humidity: Humidity, or the amount of moisture in the air, is crucial for the survival of certain organisms, particularly in terrestrial ecosystems.
Light: Light availability is essential for photosynthesis in plants, which forms the basis of the food web. Light also affects the behavior and activity patterns of animals.
Soil Composition: Soil provides nutrients and physical support for plant growth. The composition and fertility of the soil influence the types of plants that can grow in an area.
Nutrient Availability: Nutrients like nitrogen, phosphorus, and potassium are essential for the growth and development of organisms. Nutrient availability affects the productivity and diversity of ecosystems.
Water Availability: Access to water is critical for the survival of all living organisms. The availability of water influences the distribution and abundance of species in both terrestrial and aquatic ecosystems.
Biotic Factors: Interactions with other organisms, such as competition, predation, and mutualism, play a crucial role in shaping the survival and distribution of species in an ecosystem.
Disturbances: Natural disturbances, such as wildfires, floods, and storms, can create opportunities for some species while challenging the survival of others. The frequency and intensity of disturbances can influence ecosystem dynamics.
Geographic and Topographic Factors: The physical features of the landscape, such as altitude, slope, and proximity to water bodies, influence microclimates and provide diverse habitats for different species.
Climate Change: Changes in temperature and precipitation patterns, driven by climate change, can impact the survival of species and alter the timing of seasonal events.
Pollution and Contaminants: Environmental pollutants and contaminants can be toxic to organisms and disrupt ecological interactions, affecting their survival and reproduction.
The interaction of these environmental factors determines the distribution and abundance of organisms in an ecosystem and shapes the ecological dynamics of the entire community.
Deforestation, overgrazing, pollution, and climate change all contribute to environmental degradation and can lead to decreased crop yields and water shortages. These factors can all contribute to poverty, as people are unable to produce enough food to feed their families. Environmental degradation is impacting biodiversity, which is the diversity of living things at the genetic, species, and ecosystem levels. Land-based bird populations are threatened with extinction due to the loss of suitable habitat.

Land-based bird populations are threatened with extinction due to the loss of suitable habitat. Pollution, including from chemicals and waste, is a major driver of biodiversity and ecosystem change with especially devastating direct effects on freshwater and marine habitats. Plant and insect populations are dwindling as a result of the persistent usage of highly dangerous, non-selective insecticides. The two main causes of environmental degradation are overpopulation and urbanization by human activities. Some of the other reasons are due to deforestation, and soil erosion. Humans frequently abuse the environment to further their self-interest. Causes of natural resource depletion include population growth, consumer habits, industrialization, climate change, and pollution. The effects of natural resource depletion include increased costs, ecosystem dysfunction, and further climate change. Biodiversity loss is caused by five primary drivers: habitat loss, invasive species, overexploitation, pollution, climate change associated with global warming. They include factors such as light, radiation, temperature, water, chemicals, gases, wind and soil. In some environments, such as marine environments, pressure and sound can be important abiotic components. Abiotic factors include ambient temperature, amount of sunlight, and pH of the water soil in which an organism lives. Biotic factors would include the availability of food organisms and the presence of biological specificity, competitors, predators, and parasites. Environmental factors often influence traits independently of genes. Sometimes the environment changes a gene either its DNA sequence or its activity level. Either of these effects can change the proteins that are made from a gene, which in turn affects traits. Every organism has a unique ecosystem within which it lives. This ecosystem is its natural habitat. This is where the basic needs of the organism to survive are met: food, water, shelter from the weather and place to breed its young. All organisms need to adapt to their habitat to be able to survive.
