1. End poverty and hunger
Today, 1.3 billion people, 16% of the world population, continue to live in conditions of poverty, on less than 2 euros a day, which means a lack of access to food, drinking water and basic sanitation. Poverty has very serious effects on children: 22,000 children die every day from this problem, 1 every 4 seconds. 75 percent of people living in poverty are practicing agriculture; these people depend on it to survive and have two meals a day.
In this book we will see how these Tech Heroes are applying innovative solutions to make water drinkable; to preserve food in areas without electricity, and to improve agriculture by achieving a more efficient use of water, reducing the use of pesticides, or generating and providing climate information to small farmers as well as connecting those in the most rural areas of the planet, among many other things.
2. Improve health and wellness
The recent Covid19 pandemic has highlighted the fragility of our global health system. The new technological innovations developed by the protagonists of this book will allow us to quickly detect diseases such as cancer, Ebola or malaria; to transport vaccines without refrigeration; to remotely monitor people's health; to rebuild parts of our body that have been amputated; and to even convert a person’s breath into words, which can help people who are physically unable to speak to be able to express themselves.
3. Guarantee a quality education
Despite the progress made in recent years, poverty, living in rural areas or armed conflict continue to be causes for the non-schooling of children in different parts of the planet. Leaving a part of society out of education and knowledge is one of the most consequential forms of inequality. Some Heroes are changing this reality with important projects thanks to the internet and digital technology.
4. End inequality and injustice
Economic inequality has increased almost everywhere in the world with the top 1% of the population earning twice as much income as the poorest 50%. However, inequality is not just about income; it also has to do with gender. Equal access to employment and the end of discrimination against women is another objective of new technology.
5. Climate action
In our century, the effects of climate change are increasingly evident and are beginning to have very negative consequences for communities across the planet. We destroy our environment day by day and this affects our health and our lifestyle. Climate change, the exploitation of natural resources, the unsustainable production of waste, the the concentration of population in large cities, and air and water pollution pose a huge challenge for technology, but in this book we will see how it is possible to apply innovative solutions to reverse a trend that threatens the survival of life on Earth.
All of these problems are not unique to developing countries. The world is our home, and what happens in one corner of the world sooner or later affects other parts of the world. They are not local problems; these are problems of the whole of humanity. Therefore we have to stay together to change the world and make it a better place for everyone.
Young people, the post-millennial generation or digital natives, are called on to lead this change, since no one can understand better than they what to do and how it can be done. All our hopes are pinned on them.
