The destruction of nature can cause extinction in plant and animal species because when their habitats are destroyed or disrupted, they lose their sources of food, water, and shelter. This can lead to a decline in their population and eventually their extinction. Additionally, destruction of nature can also lead to the loss of biodiversity, which is essential for the overall health and stability of ecosystems. Therefore, it is true that the destruction of nature can cause extinction in plant and animal species.

The Encyclical letter "Laudato Si" is a document written by Pope Francis that addresses the need for environmental protection and sustainable development. It calls for an ecological conversion, which means a change in our attitudes and behaviors towards the environment. The letter emphasizes the interconnectedness of all living beings and the responsibility we have to care for the Earth. Therefore, the statement that the Encyclical letter "Laudato Si" invites us for an ecological conversion is true.

Plants release oxygen through a process called photosynthesis. During photosynthesis, plants use sunlight, water, and carbon dioxide to produce glucose and oxygen. The oxygen produced is released into the atmosphere through tiny openings in the leaves called stomata. The amount of oxygen released by each plant leaf can vary, but on average, it is estimated to be around five milliliters per hour. Therefore, the statement that each plant leaf gives off about five milliliters of oxygen per hour is true.

Chemical pollutants released from factories contribute to the pollution of our water bodies. These pollutants can include toxic substances, heavy metals, and other harmful chemicals that are discharged into rivers, lakes, and oceans through industrial waste and runoff. The chemicals can contaminate the water, making it unsafe for aquatic life and humans. This pollution can disrupt the ecosystem, harm marine organisms, and even pose risks to human health if consumed or used for activities like swimming or fishing. Therefore, the presence of chemicals from factories is a significant factor in the pollution of our water bodies.

Francis of Assisi is considered the patron of all ecologists because of his deep love and respect for nature. He is known for his close connection with the environment and his belief in the inherent value of all living beings. Francis of Assisi is often associated with his famous sermon to the birds and his devotion to animals and the natural world. His teachings and actions inspire ecologists to work towards the conservation and protection of the environment, making him a fitting patron for those dedicated to the study and preservation of ecology.

The South China tiger is indeed at risk of extinction. This subspecies of tiger is critically endangered and its population has drastically declined over the years. Factors such as habitat loss, poaching, and illegal wildlife trade have contributed to the decline in their numbers. Efforts are being made to conserve and protect the remaining South China tigers, but their future remains uncertain. Therefore, the statement is true.

The correct answer is CO2, Methane, and nitrogen oxides. These gases are commonly known as greenhouse gases because they contribute to the greenhouse effect, which traps heat in the Earth's atmosphere and leads to global warming. Carbon dioxide (CO2) is the most prevalent greenhouse gas and is released through burning fossil fuels and deforestation. Methane (CH4) is released during the production and transport of coal, oil, and natural gas. Nitrogen oxides (NOx) are produced by burning fossil fuels and contribute to air pollution and climate change.

Tropical forests hold the most biodiversity, with a high concentration of plants and animals. These forests are characterized by a warm and humid climate, which provides ideal conditions for a wide variety of species to thrive. The dense vegetation and diverse range of habitats within tropical forests support countless species, making them rich in biodiversity. This includes a vast array of plant species, as well as numerous animal species such as birds, insects, mammals, and reptiles. The complex interactions between these species contribute to the overall ecological balance and richness of tropical forests.

The word "Laudato si" is derived from the Italian phrase "Laudato sii" which translates to "Praise be to you" in English. This phrase is taken from the beginning of the Canticle of the Sun, a prayer written by Saint Francis of Assisi. It is commonly used as the title of Pope Francis' encyclical on the environment and climate change, where he calls for the protection of our common home and emphasizes the interconnectedness of all living beings.

Switzerland is considered the greenest country in the world due to its strong commitment to environmental sustainability. The country has implemented various measures to protect its natural resources, reduce pollution, and promote renewable energy. Switzerland has a high percentage of forested areas, efficient waste management systems, and strict environmental regulations. Additionally, the country has invested in public transportation, cycling infrastructure, and sustainable urban planning. These efforts have contributed to Switzerland's reputation as a leader in environmental conservation and sustainability.

Plants and animals cannot adapt to climate change. While some species may be able to adjust to gradual changes over time, rapid and extreme changes in climate can often exceed their ability to adapt. This can result in population declines, species extinction, and disruptions to ecosystems. Therefore, the statement that plants and animals can adapt to climate change is false.

There are approximately 50 million indigenous people living in forests around the world. This number represents a significant population of individuals who have a deep connection to and reliance on forest ecosystems for their livelihoods and cultural practices. These indigenous communities often possess traditional knowledge and sustainable practices that contribute to the conservation and management of forest resources. Recognizing and supporting the rights and voices of indigenous peoples is crucial for the sustainable management and preservation of forests globally.

The given statement is incorrect. Kerala is not a city, but a state in India. Therefore, it cannot be referred to as the greenest city in India.

The statement that around 45% of the world's oxygen is produced by just the Amazon rainforest is false. While the Amazon rainforest is indeed a vital source of oxygen production, it is estimated to contribute approximately 20% of the world's oxygen. Other sources, such as marine plants and algae, also play a significant role in oxygen production. Therefore, the given statement is incorrect.
