The number of live births per 1,000 people in a population of 2.7 is known as the crude birth rate. The number of fatalities per 1,000 people in a particular year is the crude mortality rate.

Given

Crude Birth Rate (CBR): Total live births / Total midyear population) x 1,000

CBR  =(3% of 90,000,000) / 90,000,000) x 1,000

CBR = (0.03 x 90,000,000) / 90,000,000) x 1,000

CBR = 2.7

Crude Death Rate (CDR): (Total deaths / Total midyear population) x 1,000

CDR = (2% of 90,000,000) / 90,000,000) x 1,000

CDR = (0.02 x 90,000,000) / 90,000,000) x 1,000

CDR = 2.0

Sex Ratio: The sex ratio is the number of males per 100 females in a given population.

Number of males = (Male population percentage / 100) x Total midyear population

Number of males = (45% / 100) x 90,000,000

Number of males = 0.45 x 90,000,000

Number of males = 40,500,000

Sex ratio = (Number of males / Number of females) x 100

Sex ratio = (40,500,000 / (90,000,000 - 40,500,000)) x 100

Sex ratio = (40,500,000 / 49,500,000) x 100

Spring tides occur twice a month. This is when the sun and moon exert a combined gravitational pull on ocean waters. Spring tides occur during the new moon and full moon phases of the moon. The gravitational pulls of the sun and moon combine, resulting in higher high tides and lower low tides during these periods.

A spring tide is a type of tide that occurs when the gravitational forces of the sun and the moon align and combine, resulting in particularly high high tides and low low tides.

During a spring tide, the sun, moon, and Earth are in a straight line, with the gravitational pull of both the sun and the moon reinforcing each other.

This alignment causes the ocean waters to be pulled in the same direction, leading to a greater difference between high and low tide levels.

Tourism can have visible effects on the environment, both positive and negative, depending on various factors such as the volume of tourists, type of tourism activities, and the management practices in place.

One of the most noticeable impacts of tourism on the environment is increased pollution. The influx of tourists often leads to increased waste generation, including plastic bottles, packaging, and other disposable items. Improper waste management and inadequate infrastructure to handle the increased waste can result in littering and pollution of natural habitats, including beaches, forests, and water bodies.

Additionally, transportation associated with tourism, such as airplanes, cruise ships, and vehicles, contribute to air and noise pollution, particularly in popular tourist destinations.

Another visible effect of tourism is the degradation of natural resources. Excessive water usage in hotels and resorts, especially in areas with limited water supply, can strain local resources and deplete freshwater reserves.

Unsustainable practices such as overfishing and destructive fishing methods can harm marine ecosystems and deplete fish populations, affecting the livelihoods of local communities dependent on fishing. Similarly, uncontrolled tourism activities like hiking, off-road driving, and wildlife disturbance can lead to habitat degradation and loss of biodiversity.

The construction of tourist infrastructure, including hotels, resorts, and recreational facilities, can result in land degradation and deforestation. In some cases, the construction may encroach upon sensitive habitats, disrupt ecosystems, and displace local flora and fauna.

Moreover, the demand for energy to power hotels and other tourist facilities can lead to increased energy consumption and greenhouse gas emissions, contributing to climate change.

However, it is important to note that sustainable tourism practices can help mitigate these negative effects. Responsible tourism initiatives, such as eco-tourism and community-based tourism, aim to minimize environmental impacts and promote conservation efforts.

These practices involve adopting renewable energy sources, implementing waste management systems, supporting local economies, and educating tourists about environmentally friendly behaviors.

Answer:

Long term changes in the climate of the environment

Explanation:

Climate change refers to long-term alterations in temperature patterns, precipitation levels, wind patterns, and other aspects of the Earth's climate system. It is primarily caused by human activities, particularly the emission of greenhouse gases such as carbon dioxide (CO2) and methane (CH4) into the atmosphere.

Here are some key points related to climate change:

Causes: The primary cause of climate change is the burning of fossil fuels (coal, oil, and natural gas) for energy production, transportation, and industrial processes. Deforestation, agricultural practices, and land-use changes also contribute to greenhouse gas emissions.

Greenhouse Effect: Greenhouse gases trap heat in the Earth's atmosphere, preventing it from escaping into space. This leads to a gradual increase in global temperatures, known as global warming. This warming effect is called the greenhouse effect and is essential for sustaining life on Earth. However, human activities have intensified this effect, resulting in significant climate change.

Impacts: Climate change has wide-ranging impacts on the environment, ecosystems, and human societies. These include rising global temperatures, more frequent and severe heatwaves, changes in precipitation patterns, sea-level rise, melting glaciers and ice caps, increased frequency of extreme weather events (such as hurricanes and floods), shifts in plant and animal habitats, and threats to biodiversity.

Mitigation: Mitigation refers to efforts aimed at reducing greenhouse gas emissions to prevent or minimize the severity of climate change. This involves transitioning to cleaner and renewable energy sources, improving energy efficiency, promoting sustainable land-use practices, and adopting greener transportation options.
