What Would Earth Be Like with 70% Vegetation?
Imagine a planet Earth where 70% of the surface is covered by lush vegetation, from dense tropical forests to vast grasslands. Such a scenario would be fascinating and would bring radical changes to the environment, climate, human life and biodiversity. In this article, we will explore how life on the planet would be different with such abundant green cover, addressing everything from the impact on the climate to the adaptation of the population.

1. The Climate on a Green Earth
With 70% vegetation covering the Earth, the climate would be significantly milder and more stable. Trees and plants have the ability to absorb carbon dioxide and release oxygen, which would drastically reduce greenhouse gases and help control global temperatures. This natural balance between vegetation and climate could mitigate weather extremes, reducing the occurrence of droughts and heat waves.
In addition, vegetation would influence the water cycle. With more plants and trees, evapotranspiration – the process by which plants release water vapor – would increase, contributing to increased rainfall. As a result, humidity in the air and precipitation would increase, forming a constant cycle that would keep the climate wetter in many regions, including some areas that are currently deserts.

2. The Impact on Landscapes and Biomes
If 70% of the Earth were covered by vegetation, we would see a significant transformation in landscapes around the world. Large deserts, such as the Sahara, could be replaced by lush green regions, and even arctic and subarctic areas would see more vegetation during the summer. Regions of grasslands, fields and woodlands would become much more common, while tropical and temperate forest biomes would dominate the global landscape.
These new landscapes would also transform the concept of “wilderness” for us. In such a green world, untouched areas of vegetation would be found in almost every corner of the planet. Ecotourism trips would become even more fascinating, with rich and diverse biodiversity in regions that are currently sparsely populated or arid.
3. Fauna and Species Diversity
With such a large area covered by vegetation, terrestrial biodiversity would increase considerably. Endangered species such as gorillas, rhinos and tigers could have a chance to recover, as they would have a vast and protected habitat in which to spread and thrive. This expansion of diverse ecosystems would create new ecological niches, favoring the emergence of unique species and promoting evolution.
In addition, with the abundance of vegetation and a favorable climate, many animal and plant species adapted to the arid or savannah environment could expand their ranges. The Earth would see a more harmonious coexistence between different species, where predators and prey would have more space to avoid each other, reducing conflict and increasing the survival of both.

4. The Effect on Cities and Urban Infrastructure
Cities would be drastically different, with more integration between urban areas and green spaces. One of the most obvious adaptations would be to incorporate greenery into cities, with buildings covered in plants, rooftop gardens, and extensive parks in urban areas. These green spaces would help reduce city temperatures, eliminating heat islands and making the urban environment more pleasant and sustainable.
In addition, buildings would be more focused on sustainable practices, with renewable energy and designs that favor human well-being and environmental protection. Transportation would be more efficient, with less pollution and streets with more shade from trees, which would encourage the use of bicycles and walking. A green city would provide a better quality of life and better health for its inhabitants.

5. Agriculture and Food Sustainability
Agriculture would have to adapt to coexist with natural vegetation, which could lead to the development of more sustainable agricultural practices. Food production would be strategically distributed in specific areas, while large areas of forests and vegetation would be preserved. This approach would require the use of efficient agricultural techniques and planting technologies that minimize environmental impact, such as vertical greenhouse cultivation and regenerative agriculture methods.
Another alternative would be the implementation of agroforestry systems, where agriculture and natural vegetation coexist harmoniously. These systems would allow food to be grown without the need for deforestation, favoring local food production and reducing transportation and carbon emissions. Sustainable agriculture would guarantee food supply for the population without compromising the integrity of ecosystems.

6. How Would the Human Population Adapt?
With the Earth covered by 70% vegetation, people would have a new relationship with the environment. This would encourage a lifestyle closer to nature, with greater appreciation of natural resources and sustainable development. People could live in communities close to forests and varied ecosystems, which would contribute to a more balanced and healthy life.
Furthermore, humans would need to find ways to adapt to minimize the impact on green areas, which could include ecological housing and infrastructure, designed to preserve nature. This new way of life would require a more developed environmental awareness, with a greater focus on recycling, biodiversity preservation and responsible consumption.

Conclusion: A Green and Sustainable Planet
A Earth with 70% of its surface covered by vegetation would be a much more balanced and sustainable world. The climate would be milder, with fewer extreme weather events; biodiversity would expand, allowing more species to coexist harmoniously; and cities would be greener and more integrated with nature. To ensure our survival and preserve this green planet, humans would need to adapt their infrastructure, agricultural practices and lifestyle.
This scenario offers us a vision of how life can be more harmonious when we balance our growth with respect for the environment. Living on a greener planet, human beings would have the opportunity to grow and prosper in harmony with the Earth, respecting the cycle of life and the essential role of vegetation in preserving natural balance.
